Hello,

If the user never registered (or few hours passed from its unregister) the subscription to REGINFO will return an empty body NOTIFY (no xml).

I don’t see any flag in module to force a body for this case,  as in the presence module is force_dummy_presence who can force a body on a first NOTIFY.

The RFC3680 says :

      o  Notifications triggered from a SUBSCRIBE contain full state
         (the list of all contacts bound to the address-of-record).

It appears that in this case the response is not conform to RFC.

Regards,

Adrian
